Egyptian President Abdel Fattah el-Sisi pledged to use “brute force against that small band of extremist terrorists” following a bomb and gun attack on a mosque in the Northern Sinai region on Friday which left 235 worshipers dead and over 100 injured.

Amid growing concern regarding the Islamic State terror group’s increased targeting of Christians in Egypt, displaced Coptic Christians in the country’s northern Sinai claim the Egyptian government is neglecting their plight.

Egypt executed prominent Islamist fighter Adel Habara on Thursday, state media said, days after a top court rejected his final appeal and in defiance of militant threats to ignite “a volcano of jihad” across the country.
